DBV Technologies Announces Completion of Blinded Period in REALISE Study of Viaskin Peanut

97.5% of patients continue treatment in the open-label arm of the REALISE study and will receive active treatment for a total of 36 months

DBV Technologies (Euronext: DBV - ISIN: FR0010417345 - Nasdaq Stock Market: DBVT) today announced that the blinded portion of the REALISE (REAL Life Use and Safety of EPIT) trial was completed. REALISE is the company's Phase III study designed to assess the safety and routine clinical use of Viaskin Peanut 250 mcg for the treatment of peanut-allergic children four to 11 years of age, including patients with a history of severe anaphylaxis. The Company anticipates announcing topline results from the blinded portion of the trial in November 2017.

Patients completing the double-blinded, placebo-controlled six-month treatment period in REALISE can continue receiving treatment for up to 36 months in the open-label portion of the study. The first part of the trial enrolled 393 patients, and 383 patients (97.5%) continued in the open-label portion of the study. All patients in REALISE are now receiving Viaskin Peanut 250 µg.

Dr. Jacqueline Pongracic, Head, Allergy and Immunology, Ann & Robert H. Lurie Children's Hospital of Chicago, Professor of Pediatrics and Medicine, Northwestern University Feinberg School of Medicine, and Principal Investigator of REALISE, said: "This novel study is a critical step forward in the development of Viaskin Peanut, and allows us to focus on the safety profile of this potential treatment in routine medical practice. For children and their caregivers who face the burden of coping with peanut allergy, we know that having a safe treatment is paramount."

About REALISE
REALISE is a multicenter, randomized, double-blinded, placebo-controlled Phase III study designed to generate safety data after six months of blinded treatment in patients four to 11 years of age and assess the use of Viaskin Peanut 250 mcg in routine medical practice.  At the six-month time point, patients in both the placebo and active arms continue in the open-label portion of the study, which will monitor patients for a total of 36 months of active treatment. Exploratory criteria also include scores from patients' Food Allergy Quality of Life Questionnaire (FAQLQ) and the Food Allergy Independent Measure (FAIM), as well as the evolution of peanut-specific serological markers over time. The study is conducted in 32 centers in North America. No oral food challenges are required in REALISE. Patients in the study were selected based on a well-documented medical history of IgE-mediated reactions to peanut, including children with a history of severe anaphylaxis, as well as analyses of baseline peanut-specific immunological markers. During the first six months of trial, patients were randomized 3:1 active versus placebo. Key assessments of safety parameters include treatment-emergent adverse events observed in both the placebo and active treatment groups during the initial six months, which continue to be monitored during the open-label portion of the study. DBV randomized 393 patients in REALISE.
